5 Advantages of Using Our Galvanized Steel for Rail Infrastructure

Rail infrastructure faces constant demands. Not only is it under consistent mechanical stress, but it’s also exposed to extreme weather. When deciding upon using material for rail infrastructure, it’s critical to select something that has a long service life with minimal maintenance.

Galvanized steel for rail infrastructure is an integral part of building structures that can face such challenges. It’s a proven, versatile solution not only because it can handle vibration and weight, but also for longevity and corrosion-protection.

In this article, we’ll take a closer look at the five main advantages of using our galvanized steel for rail infrastructure, as well as answer some of the most common questions we receive.

At South Atlantic, we have 2,000+ tons of galvanized steel ready to ship. You can rest assured that we meet or exceed all ASTM standards, and our 25-point QA process means you can trust our dedication to excellence—just as many national companies have for more than 50 years.

What Components of Rail Infrastructure Can Use Galvanized Steel?

A wide variety of infrastructure components can use galvanized steel. These include:

• Track components: fishplates, rail anchors, tie plates, and bolts/fasteners
• Structural supports: signal gantries, overhead line equipment (OLE) masts, and brackets
• Bridges and walkways: pedestrian footbridges, maintenance walkways, and handrails
• Fencing and barriers: lineside fencing, anti-trespass panels, and crash barriers
• Drainage systems: culverts, guttering, and channel covers
• Station infrastructure: platform components, canopy frames, and signage supports

The 5 Advantages of Using Galvanized Steel for Rail Infrastructure

1. Superior Corrosion Resistance

Rail environments subject materials to harsh and unforgiving conditions. Rain, humidity, and de-icing salts can accelerate corrosion if you do not have the protective qualities of galvanized steel working for your project. 

This rust-resistance is critical, particularly in underground or coastal rail environments, where the galvanized steel is almost constantly exposed to moisture.

2. Exceptional Longevity and Low Lifecycle Cost

Because galvanized steel has a long service life, this means pieces do not have to be replaced as frequently. This is particularly important because in many rail environments, part replacements mean taking components out of service, resulting in expensive disruption.

Although galvanized steel may involve higher upfront costs, its longevity makes it a far more economical choice.

3. Minimal Maintenance Requirements

We mentioned earlier that galvanized steel lasts a long time and requires very little upkeep. To expand on that point,  zinc has a natural ability to repair itself. This means that if the surface gets scratched or slightly damaged, it won’t automatically start to rust. The zinc coating continues to protect the steel underneath, even in areas where it has been nicked or worn.

While painted steel may require regular repairs or touch-ups, the reduced maintenance of galvanized steel means less labor costs over the life of the project.

4. Strength and Structural Reliability

Galvanized steel still has the full strength of the base steel. This means it provides consistent, reliable performance, even under the heaviest loads. It can also withstand the vibration and temperature fluctuation that is often found in railroad environments.

Galvanized steel for rail infrastructure also complies with all rail industry structural standards.

5. Environmental Sustainability

We’ve discussed the reliability and strength of galvanized steel, but did you also realize it was “green” and environmentally responsible? Not only is zinc a naturally occurring metal, but it is also 100% recyclable.

Its longer lifespan also means that there is less material replacement. This helps reduce the carbon footprint over time. 

How Long Can Galvanized Steel Last in Rail Applications?

While there are several factors that can affect lifespan, in general, galvanized steel can last 50 to 100 years. By contrast, painted steel can last closer to 20 years.

The factors that can affect its longevity include:

• The environment– galvanized steel lasts longer in low-pollution environments as opposed to harsher marine or industrial environments.
• The coating – thicker coatings last longer. 
• The location – coatings placed on items that are in more sheltered locations will outlast those that are more exposed.
